add spacelike and near-light-cone thermal QCD diagnostics Compare unresummed spectral functions against arXiv:1910.07552v2. Save run cards, numerical results, and nonfinite-sample reproducers. Document the spacelike NLO mismatch, radial-root isolation failure, and poor convergence near the light cone.
